Wideband O2

Guys has anyone installed a Wide Band O2 bung on a long tube header collector while connected up? Let’s assume I have a decent 360 angle to weld it. I really don’t want to yank the heads if I don’t have to. Just curious if this is a common practice or a definite no no.

Thanks
Yes just disconnect your battery and you can weld them on the car with out hurting anything besides burning something while welding of course.
